Japanese destroyer proposed for the Japan Maritime Self-Defense Force. The tentative name of the class, 33 DD, is derived from an estimate that it would be budgeted in the Japanese era of Heisei 33 (2021). High Speed Multi-hull Vessel Optimization (HSMVO) The joint HSMVO research is conducted by the Acquisition, Technology & Logistics Agency (ATLA) and the Naval Surface Warfare Center Carderock Division of the US Navy. Also known as the Future Multi Purpose Trimaran concept, the HSMVO design concept is based on the Independence-class littoral combat ship with its distinctive trimaran hull design, modular mission capabilities, and aluminum construction (pictured). The mission capabilities of the concept includes mine countermeasure (MCM), humanitarian assistance and disaster recover (HADR), and offshore patrol/special ops. Likewise, each configuration will consist of different weapons, equipment, and supplies. ATLA unveiled the HSMVO trimaran warship concept model at the Japanese defense trade-show MAST Asia 2017. According to Navy Recognition website, the project is set to end in 2018 and the JMSDF would ultimately decide whether to adopt the concept for development or not. To date, no decision has been made regarding the future acquisition and construction of warships based on the HSMVO design concept.
